Yes.
Each handle is retained on the shaft with a spring clip. The shafts are splined, and there is a small notch that allows the clip to lock into place (it's sort of like a C-clip but not quite...
It's possible to remove them without the "specialty tool" (a flat tool that slides underneath the handles and opens up those clips) but the tool is so cheap that you should probably just go buy one.... the local auto parts store should have it.
When you see what the tools looks like, you will probably understand better what is going on under those handles.
